What is hydrogen energy?

In simplest terms, hydrogen energy is energy derived from hydrogen. There are a number of ways in which hydrogen can be used to generate hydrogen energy. One method is hydrogen fuel cells, in which hydrogen and oxygen are combined to generate electricity, water, and heat. These fuel cells can directly generate hydrogen energy by undergoing combustion in the presence of oxygen. Hydrogen can also be used for nuclear fusion processes to generate energy, although attempts to do so are yet to succeed for a sustainable time duration (thus far, sustaining and controlling fusion is an issue).


Hydrogen energy has a number of advantages. It is very clean and does not generate any greenhouse gases. It is abundant in the universe and is more efficient than other forms of energy. Currently, though, the cost of energy production is high and large-scale production is still under study.


Hope this helps.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
